The lower .roll is shown as vertical `play `in their bearin gs, and each passes smooth. A,The upper roll may be la compound roll, throughhand is fastened by suitable nuts to a bar, s,

' one part, f, being a solid cylinderl Or wheel, and -through the oppositeendsofwhiclipa-sstwo arms,

'the other part, y, being sectional, or-'niade of two t, of a yoke, u. The arms of each yoke pass 'semicircular halves, h 1i, which embrace 1the' shaft through a bearing-piece, e, and at the bottoni of k,paudfare fastened to the wheel j' by screws or each yoke is a stirrup, -u, through which passes a bolts l. vThe sectional wheel is provided withA weighted lever, ,'pivoted atyand borne-down by e feed'-spursm,'or other devices adapted to entera suitable weight, z, the weights being. preferablyl ing andfeeding Stock of irregular cross-section, made adjustable ltovarythe stress uponth'e yokes. uponjwhic'h the plain surfaces ofthe rollswill not When the upper` roll is .passed up (by the stock) f bite 'suiiiciently vhard or upon sutlicient surface the rods lit't the screw-shafts, which shafts raise 5^, to letect the feed ofy the stock.

The boxes b2 ports d2 by screws f2 are fastened to their sup passing through suitable vslots in the supports',` and by loosening these screws the cutter-cylinder can be raised or lowered and adjusted in position by screw-shafts h?, each having a bearing in a stud, i2, projecting from the frame e?, and the screw-threaded shankl of `each working through a nut-threaded ear, j?, at the adjacent end of the yoke-frame. The eutter-cylinder mybe adjusted endwise (or laterally with respect to the frame a) by a screw-shaft,k2, having a bearing in one of the sides pf the frame a, and having a screw-threaded shank working in a nut-thread in-an ear, l2, extending down from the bottom of the frame e2, the frame being fastened in any suitable position by screws m2, passing through slots n2 of the frame c2. It will be observed that the connecting-bar ot' the journal-yoke or yoke-frame extends around the front ofthe cutter-cylinder. 'hen such a yoke hasheretofore' been employed it has connected the boxes either by extending over the cylindeil (where it is Very'mueh in the 'way of free access to the cylinder) or under the cylinder, (which locationis in some respects ojectionable,) or in rear of the cylinder, (where it is in the way ot' the pressure-bar.) By extending the yoke across in front ot' the cylinder an otherwise. unoccupied location is secured, the pressure-bar mechanism is left unobstructed7 and we secure in the frontpart of the yoke a means ot' a-ttacl.` in g shoe-pieces o2, each shoe-piece being at the foot of a vertical bar, which is secured by a suitable nut and screw to the yoke-bar, the yokebar having a slot, p2, by means of which the shoe or shoes can be moved laterally and fastened inl any. desired position. lhc shoe-bar o2 has a vertical slot, q2, by means of which, and a screw and nut, r2, the shoe may. be adjusted vertically. is mounted, and slides.on two swinging arms, t2, each pivoted to the yoke, as seen at u2, each end of the bar sliding on its arm and being fastened in position by a screw, r2. When the cuttercylinder is provided with a straight cutter for simple planing, the pressure-bar may be set close to the cylinder, but when long molding or rabbeting-cutters are used' vit may be moved out until it will clear the paths ot' rotation ofthe cuttingedge of such cutters and press upon the stock as near as can be to the -points ot' action ot' such cutters. In front of the yoke-trame c2 are cross beams or bearers 1r? i'or supporting the boxes of th'e vertical spindles .fz-2, upon which are edgeplan i ngor tonguing-andgrooving cutters. These boxes are usually made adjustable. in position, but by means of bolts, nuts, and slotted rails, and such methods of tastenin l' are not suiiicient to prcif'ent the boxes from loosening` and slipjjiing The pressure-bar s? from position. To obviate this welemploy a sup# porting-rail or bar, with fastenings which embrace the rail, making a clamp abound the entire surface. The upper boxes ofthe vertical shafts or spindles are seen at a3, and each of said boxes forms part of a clamp, b, which encompasses the supporting-rail so as to bear all' around the surface of the rail, the `rail being preferably made circular in section, although it may be of oval, lozenge, or' triangular form. Each box has a. horizontal screw-shaft, c3, extending through .it said shaft having a bearing in the Aframe a, an

by loosening the screw (Z3 of either clamp, and a,

screw, e3, that screws up against the screw-shaft the box and vertical cutter-eylinderinay bemoved and adjusted in position along the rail, as may be necessary or desirable. From each or' either box of the vertical cutter-cylinder shafts an arm, f, extends, and tothis arman adjustable table or restplate, g3, is fastened by a screw, h3, extending through a slot, i3, in the arm, the slot and screw enabling the plate to be brought .as near to the cutter-cylinder as the kind or length of cutters on the cylinder will permit. At the v end 'of the machine is seen a lower-surfacev cutter-cylinder, 7d. The boxes I3 of this cylinder are supported4 on movable plates m3, which rest on adjustable wedges n, each wedge sliding on a bed-plate, o, and having extending into its end a screw, p, which works through a nut-threaded ear, y, extending from the frame a. By turning the screw p the wedges are operated and the cutter-cyliluler shaft and cylinder k3 are thereby raised or lowered. J ust back of this cylinder aj work-supporting bar, r", is placed, this bar being made adjustable bytslots s3, and screws t3, so as to enable the-bar to' be carried up toward or away from the cylinder, iu accordance with the form ofthe cutters being used. Over the bar 1' is an adjustable bar, n3, for attachment of shoepieees ci', said bar being mounted in bearings w3, which slide on vertical posts or rods c, andl are held in adjustable position on said rods by clamp: screws y, or by suitable nuts z3, working' in' a screw-thread cut on each or either post. lhebar is pivoted 4at one end, a-s seen at a4, While itsv other end drops into slot b and is held down by a button, e, and by turning said button the bar may be swung up on the pivot a* into verticalA position to facilita-te access to the mechanism at the front part ot' the machine. In front of the cylinder k is a horizontallyswinging work-sup porting table, 14,pivoted at one end, at c, (so as to be swun gaway from the cylinder,) and fastened in position at the opposite end by ay screw, j".

. This table slides on bars y, being fastened to the bars by screws h4 extending through slots these slots and screws permitting adjust-ment of the table toward or from the cylinder in such'manner as to enable the stock to be supported close up to 'the cutting-edges ot' the cylinder-cutters to whatever extent such cutters may project or whatever form of cutters maybe interchangeably used. lhemain cutter-eyliluler flame being made adjustable laterally, we extend a guide-rail, k, under the cylinder, and' bolt its front end to a rest`or table, 1, which' is stationary as respects the frame a, and at its rear end to arest, 04, so that the lateral movement of the cutter-cylinder frame imparts no movement to the guide. By this means nice adjustment of the cutterswith respect to the gu'de may be made by adjusting the cutter-cylinder frame after theguide has been A the bevel-pinions p on the vertical few-shafts o,
